macrumors 6502a

I really need to downgrade this unit due to some older software I really need to run. I need to run Pro Tools 9 which only runs on snow leopard.

I tried booting off of the stock SL disc with no luck
I also tried creating a bootable USB drive with no luck as well, just hangs at the apple logo forever

I verified that the CD was bootable and the USB drive was also good by booting off of them from a 13" MacBook Pro currently running SL.

Is there anything I can do to downgrade this unit, or am I stuck forever!!

Thank you all for your time!!

The Mac mini was released with a later version than what you are trying to load so it won't load. Since you have a macbook pro running SL I would use that as a target disk and boot the Mac mini off the target disk - if it works then you can use Time Machine to make a backup and then restore SL on the Mac Mini. (the install software checks for valid model numbers - if it does not know the machine then it won't install).

MJL thanks for the tip. I target booted the mac mini off of the macbook pro's hdd running SL. Created a time machine backup of SL and restored the backup through mountain lion recovery and it took. It booted but it runs like garbage ha ha. I am trying to figure out if there is a way I can get this mac mini to actually use all of the hardware while running SL. Any ideas. There must be a similar "windows sysprep.exe" like tool in osx that wipes out any garbage that links to OS to older hardware.

if that's the case, then drivers would have been made for only some early 2011 model macbooks. The mac mini 2010 core 2 duo was the last to use snow leopard. the 2011 versions of the imac and mac mini came with lion. They only support lion.
